KEY-WRENCH.

SPECIFICATION forming part of Letters Patent N 0. 649,334, dated May 8,1900.

Application filed January 30, 1900. Serial No. 3,336. (No model.)

T aZZ whom it may concern.-

Be it known that I, IVER P. MELOOS, a citizen of the United States,residing at Stony Brook, in the county of Grant and State of Minnesota,have invented certain new and useful Improvements in Key-WVrenches; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart IO to which it appertains to make and use the same.

This invention relates to new and useful improvements in tools adaptedfor use in inserting keys in apertures in shafts and also for opening orspreading the ends of the key be held together and removed from theaperture in the shaft or other iron in which the key may be held.

The invention relates, further, to the provision of means whereby theclamping ends of the tool may be held at an angle to the handles,whereby the tool may be utilized to advantage in reaching keys that maybe behind other rods or inaccessible when the handles are held inalinement with the pivotal 0 members.

More specifically,the present invention consists in the pivotingtogether of two jaws, to one of which is pivoted a wedge-shaped member,while the opposite jaw on its inner face 3 5 is provided with a seriesof recesses in which the end of the key may be held While its bifurcatedend is adapted to be engaged by the wedge-shaped member after the keyhas been inserted through the aperture of the shaft for 40 the purposeof spreading the ends of the key to retain the same in a lockedrelation. The

. clamping ends of the tool are to be utilized for the purpose ofpressing the spring ends of the key together, so that the key may beeasily withdrawn from the aperture, while the handles are hinged to thejaws to adapt the invention for use in reaching and inserting the key ina shaft, which key would be inaccessible if the handles were integralwith and in alinement with the jaws.

inserted in the aperture of the shaft.

My invention is clearly illustrated in the accompanying drawings, which,with the letters of reference marked thereon, form a part of thisapplication, and in which drawings similar letters of reference indicatelike parts throughout the several views, in which- Figure 1 is aperspective view of my improved tool for inserting and removing keys inshafts. Fig. 2 is a side elevation of my tool, showing its applicationto the key to spread the spring ends of the same to lock the key inplace. Fig. 3 is an edge view showing the hinged handles of the toolbent at an angle. Fig. 4 is a side view showing the tool in position forinserting the key.

Reference now being had to the details of the drawings by letter, Adesignates one of the jaws of my tool, which has a lug A, to which ispivoted the wedge-shaped member B. The second of the two jaws O'ispivoted, as at D, to the jaw A, and on its inner face are severaldepressions or recesses E, in which the head of the key is adapted toengage when the wedge-shaped member is being utilized to spread or openthe spring ends of the key to hold the latter in a locked relation.

To the jaws A and O are hinged the handles K, each of which has acontracted end K, which is pivoted in a recess in the hinged end of thejaw, thus allowing said handles to swing on their pivots, but notlaterally. It frequently happens that with the handles integral and inalinement with the jaws keys cannot be conveniently reached, as saidkeys may be made inaccessible by reason of other rods or obstructionsbeing in the way. It is to adapt the tool for use in such contingenciesthat I hinge the handles in the manner shown and described.

The operation of the device will be readily understood. The end of thekey may be gripped by the jaws of the tool and th; key

fter

the key has been inserted in place the head of the key is to be placedin one of the recesses in the jaw O and the wedge-shaped member B isplaced between the spring ends of the key, as illustrated, and the endsare bent outward, thus locking the key in place. When it is desired toremove the key, the

clamping ends of the tool may be utilized to spring the ends of the keytogether, after which the key may be easily removed.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is

1. A key-wrench, comprising two jaws pivoted together, one of said jawshaving pivoted thereto a wedge-shaped member,'adapted to cooperate withone of the jaws in spreading or separating the ends of the key wheninserted in a shaft.

2. A key-wrench consisting of two jaws pivoted together, a wedge-shapedmember pivoted to a lug on one of said jaws, the second jaw havingrecesses or depressions on its inner face opposite said wedge-shapedmember, as set forth.

3. A wrench for inserting and removing keys, consisting of two jawspivoted together, one of said jaws having a wedge-shaped member pivotedthereto, and hinged handles pivoted to said jaws, as shown anddescribed.

In testimony whereof I aflix my signature in presence of two witnesses.
